To test if satellite-derived Sea Surface Temperature (SST) could provide a solution, two daily global SST products were compared with 18 high precision loggers deployed during 10-months in the wide Raroia atoll (Tuamotu Archipelago, French Polynesia). The Multi-scale-Ultra-high-Resolution (MUR) SST was better correlated with lagoon temperature (r > 0.97) than the Global-Foundation-Sea-Surface-Temperature-Analysis (G1SST) SST (r < 0.94). Differences between observations and MUR SST ranged between -0.75 degrees C and + 1.12 degrees C and were influenced by seasons and locations, depth, and hours of measurements. Within this uncertainty range, simulations using a Dynamic Energy Budget model predicted similar life traits of oysters. Therefore, MUR SST appears suitable to monitor lagoon temperature in wide atolls, model oyster population dynamics and assist pearl oyster research and management. specialized Sea surface temperature Satellite SST Pinctada margaritifera Dynamic Energy Budget MUR SST G1SST POLYNESIE FRANCAISE 040 126 032 160 111576 [13 ] 2020 0025-326X https://www.documentation.ird.fr/hor/fdi:010079992 10.1016/j.marpolbul.2020.111576 0025-326X [F B010079992] https://www.documentation.ird.fr/hor/fdi:010079992 https://www.documentation.ird.fr/intranet/publi/2020/12/010079992.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2021-01-14 2025-02-24 fdi:010079992 fre
